Meteorology practice test

Pass mark 75% from twenty randomly chosen questions.


#1. As a parcel of air rises, it cools by the process of:

#2. Orographically formed clouds occur:

#3. A wind whose direction has changed clockwise is said to have:

#4. You are flying at a constant indicated altitude when you enter a region of higher air pressure. Without making any altimeter changes at all, what would happen to your actual altitude?

With an increase of ambient pressure, the altimeter would indicate that you are at a lower altitude. The two hints here are that you are at constant INDICATED altitude (from your altimeter, of course) and that the subscale has not been adjusted to the new pressure. Therefore, as the altimeter starts to indicate a lower altitude, adjustments to the flight are made to return to the correct indicated altitude, when in fact you would be climbing, In reality, this would hardly be noticeable with a realistic change of perhaps a maximum of 2hPa increase in pressure over your route, which would equate to a gain of 60 feet altitude.

#5. Water has a ________ Specific Heat Capacity than land. (Fill in the missing space correctly.)

#6. On a cold, clear night, ice crystals may form on a surface directly from water vapour. What is this process called?

#7. When a wind changes direction from Southerly to South-Westerly, it is said to have:

#8. In the UK, away from exposed coasts, airmass thunderstorms are most likely to occur in:

#9. At the passage of a warm front you would expect:

#10. Take a look at this METAR: LMML 221530Z 18007KT -DZ BR OVC004 14/13 Q1003 – What Date and Time this report was issued?

#11. When is advection fog most likely to form?

#12. One hectopascal (hPa) represents a change in altitude of:

#13. The atmospheric situation where temperature increases with height is called a(n):

#14. Carburettor ice is formed

#15. In the northern hemisphere, compared to the surface, the 2000 foot wind can be expected to:

#16. In the southern hemisphere, high pressure system winds circulate in which direction?

#17. What is the wind that forms from the result of air warming on the side of a valley called?

#18. If ice forms over the static vent of an aircraft and blocks it during the climb, the altimeter will read:

#19. In the northern hemisphere, an aircraft flying from an area of high to low pressure will experience:

Due to the anti-clockwise motion of the airmass, and going towards the low pressure area, the wind will be from the left (port) causing a right (starboard) drift.

#20. The atmosphere:
